UNITED .STATES JOHN TORLINSKI, OF NANTIGOKE, PENNSYLVANIA.

ROTARY-TOOL APPARATUS.

Application led February 7, 17925. Serial No. 7,687.

fl all whom t may concern.'

Be it known that I, JOHN ToRLINsKI, a citizen of the United States, residing at Nanticoke, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Rotary- Tool Apparatus, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for operating rotary tools and particularly to a sawing or woodworking machine and has specialvreference to a mitering machine in which a circular saw is employed.

An object of the invention consists in so mounting a circular saw or other rotary tool that the same may be bodily reciprocated, and in providing adjustments whereby the saw may be adjusted in both a vertical and horizontal plane so as to cut grooves at any angle desired. The invention in many respects is an improvement over the construction shown in my Patent No. 1,522,604, issued January 13, 1925.

A further object of the invention resides in the provision of a w-ork holder for cooperation with the sawing apparatus which may be clamped to the work-table and which will hold the work edgewise in a vertical plane or iiat against the work-table in a horizontal plane.

Other objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawings in which:

Figure 1 is a front elevation of the apparatus. Y

Figure 2 is a vertical sectional View, parts being broken away. v

Figure 3 is a horizontal section taken on line 3-3 of Figure 1.

Figure 4 is a fragmentary vertical section taken on line 4-4 of Figure 1.

Figure 5 is a detail horizontal section showing the trackway adjusted 'in a horizontal plane at an angle to the main frame.

Figure 6 is a detail vertical section showing the trackway adjusted at an angle in a vertical plane, and

Figure 7 is a vertical section through the work clamp taken on line 7-7 of Figure 2.

Referring to the drawings more in detail the numeral 1 refers to a work-table, carpenters bench or the like to which the frame 2 of my sawing apparatus is adapted to be attached by means of ordinary clamps such ,as indicated by the numerals 3,. The frame 2 is preferably of rectangular formation, having spaced vertical standards and is reinforced on its top rail by means of an arch 4 in order that itmay sustain the necessary mechanism. f

The top rail of the frame 2 as well as the arch 4 are formed with aligned openings in which are located the upper extensions 5 of a carrier 8 and an adjusting boltl 7. The body 8 of the carrier comprises a graduated disc having cut-out portions to lighten the same as shown in Figures 3 and 4, and from an inspection of Figures 1 and 2 it will be observed that the adjusting bolt 7 passes through the center of this disc andl up through the top of the frame 2 and arch 4. The extensions 5, of course, are slidably mounted in the apertures above referred to and by means of nuts 9 the carrier may be locked in various adjusted positions in a vertical plane.

Rigidly connected to the lower end of the I bolt 7 is a bracket 10 provided with the downwardlyhextending arms 11 and adj acent lugs 12 carrying set screws 13, while the upper edge of the bracket is provided with L-'shaped members 14 which overhang the disc 8 and carry set-screws 15 for engagement therewith. By means of the construction thus far described it will be apparent that the bracket 10 may be adjusted vertically'through the medium of the bolt 7, and horizontally through the medium of setscrews 15 and disc 8.

Pivotally mounted within the bracket 10 is a trackway composed of upper and lower rails 20 and 21 respectively which are joined at their adjacent ends by means of the spacing members 22 which latter are integrally connected to the lower rail 21. These spacing members are pivotally connected to the downwardly-extending arms 11 of the bracket 10 by means of bolts 23 and thus form a horizontal pivot for the trackway. In order that the trackway may be locked in various adjusted positions about its pivot point the upper ends of the members 22 carry arc-shaped elements 24 which may be suitably graduated and which are disposed between the lugs 12 and the adjacent arm 11 of the bracket 10. By this construction it will be seen that the trackway may be adjusted on its pivot to the angle desired and then locked by engagement of the set- Iscrews 13 with the arc-shaped elements 24.

.This trackway which is formed of the suspended above the work table or clamped vvhandle `59 and bolt 38.

rails 2O and 2l supports acar'riage 25 vi'ii which is mounted a motor 26 and gearing 2T for operating` the circular saw 2S. It will be understood, ofcourse, ythat while the saw is shown as operated by electricity it may also be operated by hand or other'vpow'er-as desired.

For the purpose oil properly 'clampingI the material to be eut or grooved I have provided an' attachment for the work-table which is shown in Figures 2 and 7 and indicated generally by the iiumeralBO. This attachment includes a vertically extending standard or upright 3l which may be secured to'the work-table by means of the clamp 32. A laterally extendingarm 33 is formed on the upper end of' the standard 3l and carries at'fits tree end va 'downwardlyextendi'ng'clainp'element 34, which is adapted tor cooperation with the clampmember L35 which is slidably mounted ontlie arm 33. The clamp element 35 is grocved at its upper end as indicated at 3G i'for reception ct thetwo edges of the arm 33 which form a trackway therefor, and is provided with an extension 37 Whicliextciids .upwardly between these edges. This extension is pro- 'vided'with an aperture ioi' reception ot the `screwbolt38 which is mounted in the upper end ot the standard 3l and carries a handle 39 for its operation.

By the construction just described Vit will be fc'lea-i" that the material to be cut'may be 'readily held in suspended position'ab'ove the .table bv a proper manipulation ot Vthe l? or certain yclasses `of work it'is sometimes ldesirable to clamp Ehe'b'oard or the like 1directly vto the table and for this purpose /I'have pr'cvided athreaded bolt or vise 40 which vis Ythreadedthrough an aperture inthe lug 41 which Aextends beyond the Yclamping` element lSt and 'forms an integral part-ot` the arm y33.

Fromthe 'toregoin` descriptiontalren in connection with the acccinpaiiying` dra'wiiigs /itnwill be seen that I have devised an eX- ceedingly simple Vyet reliable construction versally adjustable, -and also a` novel construction for cooperation ,therewith byv means .oft .whichthe workmay be easily yand quickly von the surface thereof.

In accordance withthe patent statutes I have describedwhat Iv now' believefto be the bestv embodiment of the invention, but I do not wish to be understood thereby as limiting myself or 'thescope'of the invention, as many changes and modiiications may be made without departing` from the spirit ot the invention; all such I aim to include in the scope of theappended claims.

What I claim as new and desire Yto secure by Letters Patent is:
